Researchers at Sandia Laboratories are getting closer to nuclear fusion that will produce more energy than it takes to create the fusion reaction! They are very close to the break even point.
Magnetically imploded tubes called liners, intended to help produce controlled nuclear fusion at scientific "break-even" energies or better within the next few years, have functioned successfully in preliminary tests, according to a Sandia research paper accepted for publication by Physical Review Letters (PRL).
Sandia researcher Ryan McBride pays close attention to the tiny central beryllium liner to be imploded by the powerful magnetic field generated by Sandiaâ€™s Z machine. The larger cylinders forming a circle on the exterior of the base plate measure Zâ€™s load current by picking up the generated magnetic field.

To exceed scientific break-even is the most hotly sought-after goal of fusion research, in which the energy released by a fusion reaction is greater than the energy put into it â€” an achievement that would have extraordinary energy and defense implications.

That the liners survived their electromagnetic drubbing is a key step in stimulating further Sandia testing of a concept called MagLIF (Magnetized Liner Inertial Fusion), which will use magnetic fields and laser pre-heating in the quest for energetic fusion.

In the dry-run experiments just completed, cylindrical beryllium liners remained reasonably intact as they were imploded by huge magnetic field of Sandiaâ€™s Z machine, the worldâ€™s most powerful pulsed-power accelerator. Had they overly distorted, they would have proved themselves incapable of shoveling together nuclear fuel â€” deuterium and possibly tritium â€” to the point of fusing them. Sandia researchers expect to add deuterium fuel in experiments scheduled for 2013.
